摘要： A distributed control system permits local or remote control of equipment. The distributed control system provides a communication bridge through a local control panel between a non-real-time network, such as an Ethernet, and a real-time network, such as a controller area network. Both soft real-time and hard real-time networks are suitable, but hard real-time is preferred. The system uses multiple distributed control units to control various equipment components and is thus highly expandable. The distributed control system may be applied in any environment. When applied to a skid-mounted coiled tubing unit, the distributed control system reduces the amount of hydraulic hose required and therefore makes set up and take down shorter and more economical.

摘要： Water-based fluids that can viscosify under shear or can produce a gel or form a gel under shear are obtained by dissolving polymers in an aqueous phase. These polymers comprise three types of functional groups: non-ionic functional groups that are hydrosoluble at the temperature under consideration, ionic functional groups, and functional groups that are hydrophobic at the temperature under consideration. These three types of functional groups can be distributed or spread in a random distribution along the polymer chain. A slightly block distribution is acceptable. For applications to oil wells, functional groups are used which exhibit LCST (Lower Critical Solution Temperature) behavior (i.e., a low critical solution temperature) instead of hydrophobic functional groups. At temperatures below the LCST, the functional groups are hydrophobic.
摘要翻译：通过将聚合物溶解在水相中，可以获得在剪切下粘稠或可以产生凝胶或在剪切下形成凝胶的水基流体。这些聚合物包括三种类型的官能团：在所考虑的温度下可溶于水的非离子官能团，离子官能团和在所考虑的温度下是疏水的官能团。这三种类型的官能团可以沿着聚合物链分布或分布在随机分布中。稍微块分布是可以接受的。对于油井的应用，使用显示LCST（较低临界溶液温度）行为（即低临界溶解温度）而不是疏水官能团的官能团。在低于LCST的温度下，官能团是疏水的。

摘要： An interactive apparatus and associated method transmit wellbore information, in real time, to a client approximately simultaneously with a generation of the wellbore information at a well site, in response to interactive requests made by the client at a workstation computer over the internet. In addition, the interactive apparatus and associated method generate and display, on a client's display screen, a unique 'display window' when the client is accessing the internet using only the client's 'browser' software already installed on the client's personal computer. As a result, there is no need to purchase or license any additional software to display the unique 'display window' on the client's display screen. The 'display window' displays 'real-time' wellbore information to the client approximately simultaneously with the generation of that wellbore information, the 'display window' displaying both 'real-time' digital 'wellbore data' information and 'real-time' graphical 'wellbore data' information for displaying the 'real-time' wellbore information.
