Mud Recycling System for Offshore drilling2013-09-14
Compared with drilling on ground, the offshore drilling has higher requirement about the mud recycling equipment.
The design of drilling mud tank needed to achieve the following demands:
1 Drilling mud tank should contain the maximum circulating volume of drilling fluid in drilling process.
2 The whole intensity of mud tank should satisfy the demands of hoisting, transport and using drilling fluid with 2.5g/cm³.
3 According to the requirement of technological process, between each cabins should be installed overfall and communicating pipe.
4 Every bay should be installed cleaning port, the lower edge of the opening should be leveled with tank bottom, and can be below the tank bottom.
5 All of the sealing elements needed to satisfy oil resistance, acid-resisting, alkali-resisting, and H2S resistance, and can meet the requirement of using all kinds of drilling fluid.
