摘要： It is proposed a new fluid loss control agent useful for the cementation of oil or gas wells. This fluid loss control agent consists of a mixture of a styrene-butadiene latex and a high molecular weight water-soluble polymer such as a copolymer AMPS-Am. The addition of the water-soluble polymer allows drastic reduction of the quantity of latex required to achieve fluid loss control performance and even gas migration control.

摘要： A two step process for treating an oil or gas well. The first step uses a cross linking agent, such as borax, as a preliminary wash for the well following drilling. The cross linking agent cleans the well of excess mud and pre-coats the tubing and the formation surfaces with the cross linking agent. The second step introduces a cement-polymer mixture into the well. A polymer, such as for example polyvinyl alcohol, that undergoes cross linking when exposed to the cross linking agent is employed. When the polymer comes into contact with the cross linking agent in the well, cross linking of the polymer occurs. This cross linking helps to prevent fluid loss into the formation. Also, because the cross linking agent wash previously cleaned the surfaces of the tubing and the formation, better bonding between the cement and the surfaces of the tubing and the formation occurs.

摘要翻译： 用于处理油或气井的两步法。 第一步使用交联剂，如硼砂，作为钻井后的井的初步洗涤。 交联剂清洗多余泥浆的井，并用交联剂预涂布管道和地层表面。 第二步将水泥 - 聚合物混合物引入井中。 使用当暴露于交联剂时经历交联的聚合物，例如聚乙烯醇。 当聚合物与孔中的交联剂接触时，发生聚合物的交联。 这种交联有助于防止流体流入地层。 而且，因为交联剂洗涤事先清洗了管道和地层的表面，所以发生了水泥与管道表面和地层之间的更好的结合。

摘要： A modified polyvinyl alcohol (PVA) protected with a protecting group of the present invention is one wherein an amount of high-molecular weight body components of the modified polyvinyl alcohol having a weight-average molecular weight of 250,000 or more as determined by polyethylene glycol standards according to a gel permeation chromatography is 1000 ppm or less in the modified polyvinyl alcohol. The modified PVA is prepared by removing a metal ion and an acid from the modified PVA such as acetalized PVA with ion exchange treatment and then heat-treating at 80° C. or higher. An auxiliary for fine pattern formation of the present invention comprises the aforementioned modified PVA, a water-soluble crosslinking agent, and water or a mixed solvent of water and a water-soluble organic solvent. The auxiliary for fine pattern formation is applied over a resist pattern 3 and a coated layer 4 is formed thereon. Then the resist pattern 3 and the coated layer 4 are heated and thereby an acid is diffused from the resist pattern 3 to the coated layer 4. As a result, the coated layer in the vicinity of the resist pattern surface is crosslinked and cured by the diffused acid. The coated layer is developed to form a hole pattern having crosslinked and cured layer on the resist pattern, of which the hole size is less than a limit resolution of the wavelength of a light-exposure and which have no development defects.
