In oil gas drilling, good condition drilling mud performance is the preconditions of improving drilling speed, reducing drilling cost, preventing well accidents and protecting hydrocarbon reservoir. While solids control system is the guarantee of maintaining ideal performance of drilling mud. This essay will mainly concludes solutions to improve
drilling mud solids control production efficiency and realize economic production.
With the development of modern drilling exploration, the drilling well depth is increasing and at the same time difficulties on complicated drilling conditions, technical difficulties on deep well, super deep well, horizontal well and unbalanced well is more and more obvious in the practical drilling, but this is the power to improving drilling technique, and with these years development, drilling techniques have been obviously improved. Actually, there is misunderstanding points within the system. According to expert analysis of these misunderstandings, production needs as well as economic improvement would be obtained in the future productions.
The following description will mainly focus on solutions to these misunderstanding points.
Make sure that the solids control system processing capacity is as double as the well uses.
Choose well performed and proper drilling mud desander,
desilter, using series connection to reach wonderful desilting and desanding effect.
Adopt middle speed and high speed
decanter centrifuge to improve the servicing life of other units used in the following steps. As analysis statistics show that 90% daily maintenance cost focuses on solids control processing and 75% cost is spent by drilling mud weight. Therefore, correct selection and application of solids control system and equipment helps separating drilling cuttings and reducing the consumption of drilling mud and relative materials. And this is the just the reflection of economic development of industry production and improvement production efficiency.
