摘要： Methods and systems for conducting liner drilling and subsequent completion of the drilled section by cementing and anchoring the liner into place. The methods and systems prevent the liner from being cemented in in a bent or corkscrewed configuration. Additionally, there are no exterior components associated with the liner during drilling so as to allow relatively unrestricted return of drilling mud and cuttings.

摘要： A pressure-boosting apparatus particularly amenable for use in downhole applications is disclosed. The pressure-boosting apparatus employs an unbalanced piston which is initially fixated in a run-in position. The piston has a flowpath therethrough in which is mounted a check valve. Initially, pressure is applied to above and below the piston which results in an unbalanced force on the piston due to its configuration. Flow to the tool initiates its actuation at this time. When the unbalanced force reaches a predetermined level, the piston is no longer fixated to the housing and begins to accelerate. Acceleration of the piston closes the check valve due to the sudden decrease in pressure behind the check valve and an increase in pressure in front of the check valve as the fluid volume in front of the piston is compressed. Due to the proportional relationship between pressure and area, a magnification of force originally delivered by the pump is achieved for completion of the setting of a downhole tool such as a packer or bridge plug or the like.

摘要： A system for enhancing hydrocarbon production in long and deviated subterranean wells. Gravel is placed in the annulus between the screen liner and the borehole, together with annular isolation elements. Selective flow control is achieved. Sequential control or commingled production is achievable from multiple producing intervals of the borehole. A differential valve is incorporated in the screen liner service string to allow for gravel placement across multiple screen-liner sections, separated by annular isolation elements in a continuous one stage placement operation, thereby reducing time and complexity of such operations.

摘要： A drilling assembly supports a liner for making a wellbore. The BHA comprises a pilot bit and a reamer above it that is larger in diameter than the suspended liner. If the BHA needs to be pulled out, the reamer is brought into contact with the liner and a latch mechanism between the two engages as another latch that had held the reamer bit to the BHA is released. The reamer bit stays with the liner as the BHA is pulled and later reinserted. On the way in the BHA latches to the reamer bit which then unlatches from the liner bottom. Preferably, splines and a shoulder on the BHA are used to drive the reamer bit as opposed to any power being transmitted through the latch between the BHA and the reamer bit. However, the latch mechanism between the BHA and the reamer bit could also provide torque and weight on bit for drilling operations. The process may be repeated.
摘要翻译： 钻井组件支撑用于制造井筒的衬管。 BHA包括一个导向钻头和一个位于其上面的扩孔器，其直径大于悬挂的内衬。 如果需要将BHA拉出，则铰刀与衬套接触，并且两者之间的锁定机构接合，将另一个将铰刀钻头固定在BHA上的闩锁释放。 随着BHA被拉动并随后被重新插入，铰刀钻头停留在衬管上。 在BHA的路上锁定到扩孔钻头，然后从底部底部脱落。 优选地，BHA上的花键和肩部用于驱动铰刀钻头，而不是通过BHA和铰刀钻头之间的闩锁传递的任何动力。 然而，BHA和铰刀钻头之间的闩锁机构也可以为钻孔操作提供钻头的扭矩和重量。 该过程可以重复。
