Drilling fluid solid control system is one of the important parts of modern drilling rig. With the continuous development of drilling technology, drilling process of solid is the effect of the control system is also put forward higher requirements. In China since the late 1970 s began to jet drilling method and introducing foreign part of the solids control equipment has come, in the long-term practice, in addition to improve on the performance of the drilling shaker, on how to install solid control system has been a lack of thorough system analysis.
In recent years, domestic drilling equipment of form a complete set, though in a continuously updated, but the focus of the update is concentrated in the hoisting system, power units, transmission system, control system, the development of the base and so on, and the solid control system main equipment, the overall process, separation principle, especially the optimization of the whole system (processing power matching, the service life), and how to install solid control system, such as relatively insufficient research and analysis. Reference API. RP. 13C recommended practice, all cannot meet the requirements in many ways, even on how to install solid control system there are some wrong understanding and practices. Users should further improve the efficacy of the whole system, correctly grasp how to install solid control system, eliminate drilling fluid and equipment and the mutual influence between solids control equipment, to meet different geological condition and drilling operation stage of the solid control system requirements. Strengthen the key equipment of the research and development, fundamentally solve the drilling speed and drilling quality returns, drilling, drilling cost and environmental problems, from how to install solid control system to improve the performance of the solid control system and service life. Therefore, the optimization of drilling fluid solids control system and know how to install solid control system, to improve China's oil drilling system equipment development level, improve the efficiency of drilling rig system has important realistic meaning and good economic and social benefits.
At present, the domestic engaged in the solid control system and equipment manufacturer is numerous, solid control system of the product quality and performance difference is bigger also, on how to install solid control system lack of uniform standards. Is solid control system of the circular tank, generally is put forward by the user capacity and the main structure size requirements, designed and manufactured by different manufacturers. The drill to same type of different users, and even different batches of the same user, its main dimensions, and technical parameters and on how to install solid control system is different. Series, with the same model of products, its main components are the lack of interchangeability, many brand series products of versatility. The production status, lack of market competitiveness, is not adapted to the development in the field of drilling; more can't satisfy the development of offshore drilling operation to the overall performance of the solids control equipment requirements, serious damage to the interests of users.
With the rapid development of drilling engineering technology in China, the solid control system of manufacture and to how to install solid control system understanding had certain improvement. The solid control system has been largely configuration the tertiary purification equipment, deep well drilling in most of the configuration category five purification equipments. But since most of the drilling production personnel on how to reasonable configuration, how to install solid control system, there are many misconceptions, and there is no uniform standard can be performed, thus cause the arbitrariness of solids control equipment and poor equipment maintenance level, cannot achieve the best performance of the whole system, any solids control effect. In addition, the scene can often see some drilling crew part of solids control equipment in the stopped state for a long time, make the drilling fluid cannot get effective treatment. And the use of a centrifuge increase drilling fluid, handling of the solid content is not controllable, the waste of drag reduction agent and a large number of fillers.
