Casing pressure,Casing head pressure

井口套管和油管环形空间内的压力。

Da Niudi DF2 gas well study shows the average overall heat transfer coefficient drops from 43w/m2.k to 2.57 w/m2.k when the casing head pressure decreases from 16MPa to 0.11MPa.

大牛地DF2井计算表明：当套压由16MPa降低至0.1MPa，井筒总传热系由34 W/降为2.57 W/，井口流温由6.2℃上升至20.2℃，有效的防治水合物在井筒中生成

The idea that the casing shoe resistance and the crushing strength of the LCM must be considered when design the density of the drilling fluids is presented. It holds that the surface pressure should be junior to the crushing strength of LCM, in order to prevent the formed bridge plug from crushing.

提出设计井内堵漏钻井液密度时，必须同时考虑套鞋处破漏压力和桥接材料的抗压强度对井内压力的限制；认为提高压力敏感性裂缝地层承压能力的堵漏作业时，井口压力应不超过桥接材料的抗压强度，以保证裂缝内已形成的堵塞隔墙不被破坏。

More than 10 minutes, Peng Zhixiang to Anyuan coal mines, mine in Anyuan leaders Wu Bangguo visited the well-head pressure fan room, floor repair shop, transportation lines and coal washery coal-Ping, to insist on the production of the cadres and workers holiday greetings , and in the field and Anyuan mine who led the research work issues.
