    摘要： A method of controlling and delaying the inversion of a drilling fluid and the wettability of a filtercake by using a delayed phase changing agent. The filtercake is preferably formed while drilling a subterranean formation using a drilling fluid includes: an oleaginous fluid; a non-oleaginous fluid; an amine surfactant having the structure: wherein R is a C12–C22 aliphatic hydrocarbon; R′ is an independently selectable from hydrogen or C1 to C3 alkyl; A is NH or O, and 1≦x+y≦3. In the method, the filter cake is exposed to a delayed phase changing agent selected from the group consisting of aliphatic amine acids, salts of aliphatic amine acids and combinations thereof. In one preferred illustrative embodiment, the delayed phase changing agent is delivered in the form of a pill, the pill including a carrier fluid, a viscosifier and the delayed phase changing agent. The delayed phase changing agent may be selected from ethylene diamine tetraacetic acid, alkali metal salts of ethylene diamine tetraacetic acid and combinations of these and similar compounds.

    摘要： A collapsible cart for carrying one or more golf bags while playing golf including a pair of large diameter wheels having an inflated pneumatic tire on each wheel and a foldable, lightweight, rigid frame of unique construction for positioning in a compact condition with folding of the frame between collapsed and extended positions enabling attachment and detachment of the independent wheels. The cart includes a unique U-shaped handle to facilitate movement of the cart by either pushing the cart or pulling the cart in the nature of a rickshaw. The handle is also pivotal for movement to a compact position alongside the frame. A pivotal bar is mounted on the frame to support the bottom portion of one or two golf bags and a tie cord is provided on the upper portion of the frame to retain the upper end portion of the bag or bags on the frame. Detachment of the frame from the wheels enables storage of the cart in relatively small spaces.
