Bntonite plays an essential role in traditional polymer and plymer slfonate drilling fluid as a kin of indispensable treating agent. However, research shows thatparticles of bentonite with full hydration and high dispersion affacts the drilling rate greatly far more than the effect of cuttings and weighting materials. Brine has a high salinity, which makes brine drilling fluid inhibitiveand able to suppress hyration and swelling of shale, keep borehole……
Polymer sulfonate drilling fluid is added into sulfonatetreating agent on the base of polymer drilling fluid, which can improve quality of mud cake and borehole stability, significantly decrease complexities such as hole-wall collapsing and jamming of drilling tool in deep wells, and finally improve the drilling success ratio to a large extent. Polymer sulfonate drilling fluid has been developped for decades and been one of the best choice of drilling fluid for the drilling company, the technique of which is reletively mature and the sulfonatetreating agent of which is easy to get.
YLHY can provide a series of drilling rigs for 2000m to 9000m well’s drilling.Annual maximum drilling capability can reach 400,000meters.By which we can complete the project of drilling and completion service for wells whose TD are less than 9,000m,including vertical wells, horizontal wells, cluster wells and multi-lateral wells
The main part of the turbodrill is a turbine. Each stage of turbine is composed of one stator and one rotor. Because the power output of one stage of turbine is too small, such a turbodrill is usually combined by hundreds of turbines with the same structuresin series. In order to sustain large axial load, a thrust bearing is equipped inside the turbodrill. In addition, there are two intermediate bearings equipped at one third and two thirds of the main shaft respectively to correctly support the main shaft. The basic parameters representing the performance features of the turbodrill include torque, revolving speed, output power, flow, pressure drop and efficiency. In particular, torque, revolving speed and output power are the most parameters representing the power capacity and features of the turbodrill. Flow, pressure drop and input power are important conditions for ensuring its operation with high proficiency and rapid drilling with proper use of such turbodrills.
The PZIG tool is an instrumented sub that operates directly above thedrill bit to provide real-time inclination and gamma ray easurements.These measurements are used to help determine well path placement anddetermine position real-time while drilling. The PZIG sub is an accurate,cost effective geosteering solution whether drilling for optimum reservoir drainage, setting casing, build rates, or just to determine position realtimewhile drilling.
